IMPROVEMENT IN LUBRI'CATING SPINDLES.

Specification forming part of Letters Patent No. 136,504, dated March 4,1873.

To all whom it may concern:

Be it known that I, JOHN GOULDING, of Worcester, in the county ofWorcester and State of Massachusetts, have invented certain Improvementsin the Mode or Means of Lubricating Spindles, of which the following isa specification: v

My invention consists inthe arrangement, within an oil-chambersurrounding the ordinary spindle used in cotton and woolen mills, ot'one or more absorbent disks or layers of material, so as not to touchthe spindle, for retaining a supply of oil, in connection with asuperimposed disk or piece, so arranged as to touch the spindle at oneor more points, but slightly, to feed the oil gradually to the spindle,and thus keep it constantly lubricated, as hereinafter more fullyexplained.

Figure lis a side elevation of a portion of a spindle and its bearingwith myimprovement applied, the oil-chamber and lubricating devicesbeing shown enlarged in section for the purpose of more clearlyillustrating my invention. Fig. 2 is a top-plan view taken on the linea' :r of Fig. l; and Fig. 3 is a side elevation of a spindle, showingthe lubricating device applied to the step, a portion being broken awayto more clearly illustrate it.

In constructing my device, I form a recess or chamber in the upper endof the bearing B, as shown in Fig. 1. I then provide any required numberof disks, C, having a hole cut centrally through them, somewhat largerin diameter than the spindle A, so that when these disks C are placed inthe recess they will not come in contact with the spindle,

- there being a free open space left between the inner edge of the disksand the spindle, as shown in Fig. 1. These disks may be of any softporous or absorbent material that will readily absorb and retain theoil, their function being simply to retain or store up a supply ot' oil.Upon these I place another disk,`

E, which, as shown more clearly in Fig. 2, has its central hole cuteccentrically, so that its inner edge will slightly touch the spindle,as there represented. Upon this I place a metallic disk, I, with acentral opening larger than the spindle, so as not to touch it, thisdisk I having one or more holes, O, through it to receive the oil, whichis poured therein, and soaks into the disks below. This metal disk Isimply serves to hold the others down in place, and is not absolutelynecessary, though I prefer to use it. A cap, D, is placed loosely overthe whole as a cover to exclude dust from the oil-chamber, and which canbe easily raised when necessary to supply the chamber with oil.

It will be seen from the above description that the disks G will retaina considerable quantity of oil, which, by capillary attraction, will beconveyed to the upper disk E, which, in turn, will convey it in minutequantities to the spindle at the point of contact therewith, and thatthus the latter will be kept constantly and uniformly lubricated. Thesame device is applied also to the step which supports the lower end ofthe spindle, asshown, in Fig. 3.

It is obvious that instead of using disks any suitable material may beemployed, and that instead of an eccentric hole in the disk E, any otherplan may be adopted for forming a contact with the spindle--as, forinstance, a small projecting point, or any similar arrangement-theobject being to form a contact with a small portion only of the spindle,so as to feed the oil very gradually thereto. I prefer, however, to usesoft felt as the material, and to make them in the form of disks, asrepresented, because they can thus be made by machinery with uniformityand rapidity.

Having thus described my invention, what I claim is- The arrangement,within an oil-chamber or recess surrounding the spindle A, of anabsorbent disk or layer, C, which shall' not be in contact with thespindle, in combination with a disk or layer, E, which shall slightlytouch the spindle, all substantially as and for the purpose set forth.

JOHN GOULDING.
